enum Cairo::HintMetrics

Specifies whether to hint font metrics; hinting font metrics means quantizing them so that they are integer values in device space.

Doing this improves the consistency of letter and line spacing, however it also means that text will be laid out differently at different zoom factors.

Enumerator:

  HINT_METRICS_DEFAULT | Hint metrics in the default manner for the font backend and target device.
  HINT_METRICS_OFF | Do not hint font metrics.
  HINT_METRICS_ON | Hint font metrics.

enum Cairo::HintStyle

Specifies the type of hinting to do on font outlines.

Hinting is the process of fitting outlines to the pixel grid in order to improve the appearance of the result. Since hinting outlines involves distorting them, it also reduces the faithfulness to the original outline shapes. Not all of the outline hinting styles are supported by all font backends.

New entries may be added in future versions.

Enumerator:

  HINT_STYLE_DEFAULT | Use the default hint style for font backend and target device.
  HINT_STYLE_NONE | Do not hint outlines.
  HINT_STYLE_SLIGHT | Hint outlines slightly to improve contrast while retaining good fidelity to the original shapes.
  HINT_STYLE_MEDIUM | Hint outlines with medium strength giving a compromise between fidelity to the original shapes and contrast.
  HINT_STYLE_FULL | Hint outlines to maximize contrast.

enum Cairo::LineCap

Enumerator:

  LINE_CAP_BUTT |
  LINE_CAP_ROUND |
  LINE_CAP_SQUARE |

enum Cairo::LineJoin

Enumerator:

  LINE_JOIN_MITER |

  PS_LEVEL_2 |
  PS_LEVEL_3 |
